My family had the opportunity to visit Alaska in all its amazingness. While travelling through the state, we decided to visit the Aleutian Islands.
The Aleutian Islands is a ocenanic convergent-plate margin that was formed from the Pacific Plate being sunk under the North American Plate (compression). In this zone, the ocean plates melting and the molten rock pushing to the surface in reation from active volcanoes, is what structed the Aleutian Islands.

These islands consist of mostly volcanic rock, which makes sense, as there are over 40 active volcanoes today. As the islands run along the Denali faults, which are strike-slip faults, it is not uncommon to have active earthquakes and volcanoes.
